Abstract
The utility model relates to a negative-pressure-adjustable aspirator hose, which comprises a hose and is characterized in that an air inlet pipe is arranged on the hose, and a switch and an air filter are arranged on the air inlet pipe. In the use process, the pressure is set to 400, the switch arranged on the air inlet pipe can be opened when the pressure accidentally reaches 600, air is released in the hose through the air filter, and the effect of reducing the negative pressure is reached. The negative-pressure-adjustable aspirator hose has the beneficial effects that the structure is reasonable, the operation is convenient, the injury on the endometrium of a patient caused by excessive negative pressure is avoided, and convenience is also brought to the operation of medical personnel.
Description
Technical field
This utility model relates to a kind of medical apparatus, specifically a kind of suction pump flexible pipe of adjustable negative pressure.
Background technology
At present, known department of obstetrics and gynecology clinically are when doing the induced labor operation, and the flexible pipe of vacuum extractor can sustain unlimited negative pressure; Because pressure is will be by doctor oneself control, present equipment pressure is difficult to grasp, as wants to get to 400 to pressure; Accidentally just last 600, also have no idea to fall pressure, do like this and cause very macrolesion for sometimes patient's endometrium; Not only cause suffering, brought inconvenience also for medical personnel's work to the patient.
Summary of the invention
This utility model technical problem to be solved is the deficiency that overcomes above-mentioned prior art, and a kind of simple structure is provided, the suction pump flexible pipe of adjustable negative pressure easy to use.
This utility model solves the technical scheme that its above-mentioned technical problem adopted: a kind of suction pump flexible pipe of adjustable negative pressure, it comprises flexible pipe, it is characterized in that: on said flexible pipe, be provided with air inlet pipe, air inlet pipe is provided with switch and air filter.Get to 400 to pressure as wanting during use, accidentally gone up 600, just can open the switch that air inlet pipe is provided with, in said flexible pipe, exit, reach the effect that reduces negative pressure through air filter.The beneficial effect of this utility model is: rational in infrastructure, easy to operate.Avoided excessive, caused damage for patient's endometrium, also brought convenience to operation of medical workers because of negative pressure.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Accompanying drawing is the overall structure sketch map of this utility model.
Among the figure: 1. flexible pipe, 2. air inlet pipe, 3. switch, 4. air filter.
The specific embodiment
